[...] I have ran Nitdroid for a while. Choppy as hell on a N9 as project butter won't work. Voice calls don't work but that's kind of expected. It's nowhere near as smooth on a N9 as a Nexus. Apps seems to run well though. It would be useful for me if the headphone jack worked so i could play emulators but they just won't work unfortunately. Nor does charging. Hopefully fixed for future versions.
